Title: Active tag for electronic designs and intellectual property cores
Inventor: KEAN THOMAS A
IPC: G06F17/50
Filed: 2007-12-06
Abstract: A security tag for electronic designs implemented on integrated circuits (eg ASIC, FPGA) may use a thermal transmitter (30) to transmit tag data to an external sensor. The security tag (20) is activated by an activation code sent to the security tag from an external which indicates the presence of the electronic design to the external detector, for transmitter (alternatively the tag may be continuously on). The security tag transmits data purposes of detecting and preventing unauthorized use of the electronic design. The security tag may use changes in temperature to receive the activation code from the external transmitter, and to send the security tag data to the external sensor (other signally can be used). The security tag may use the electronic design associated with the security tag to generate the signals used to transmit the tag data. Alternatively, the security tag may use a dedicated heat generator(30), such as a collection of ring oscillators, to send these signals. The security tag may use a thermal receiver such as a ring oscillator to receive a thermal signal bearing the activation code from the external transmitter. The security tag may be used to identify the CAD tool used to design a given circuit.

Title: Retractable lifting blades for aircraft
Inventor: GERBINO ALLEN J
IPC: B64C27/30
Filed: 2006-12-20
Abstract: A rotor blade assembly for providing vertical lift to an aircraft, having a rotor head and a plurality of blades, with each blade attached to a mechanism such as a cam surface, whereby movement of the mechanism causes the radial distance between the distal tip of the attached blade and the center of the rotor head to alter, decreasing or increasing the length of the lifting surface. The blades are moved from a fully extended position providing maximum lift, to a retracted position in which the blades are removed from the airstream. The pitch of the blades may be controlled by a pitch controller to achieve full helicopter responsiveness. A plurality of bladeletts may be positioned near the outer periphery of the rotor head. When they are moved into the airstream, passing air impacts the bladeletts exerting a pressure, causing rotational movement of the rotor blade assembly.

Title: Heating and cooling blanket
Inventor: MAGRATH JOHN CHRISTOPHER
IPC: A47G9/02
Filed: 2008-07-17
Abstract: A heating and cooling blanket for a bed comprises a matrix of small diameter flexible tubes `k' embedded within a blanket `j' through which a heated or cooled fluid is circulated. The fluid may be heated or cooled by passing it through a metal block `f in thermal communication with a thermoelectric heat pump `e', such as a Peltier heat pump. Preferably, one side of the heat pump is attached to the metal block whilst the other side of the heat pump is connected to a heat sink 'g'. A fan `h' may be used to provide forced air cooling of the heat sink. Preferably, a voltage polarity change over switch `d' is activated to switch the heat pump between heating and cooling, where a time delay may be applied before the polarity change over occurs. The fluid may be circulated around the blanket by a pump `i' and the temperature may be controlled by a thermostat 'c'. The heat and cooling blanket arrangement is preferably powered by a low voltage power supply `a' which enables the blanket to be safely used whilst occupied, without risk of electrocution or fire. In use, the blanket not only provides a warm bed in the winter months but can also provide a cool bed during the summer months.

Title: Hydroformylation process and specific phosphine containing catalysts for this process
Inventor: WINKLE JOHN LOUIS VAN
IPC: C07F9/6568
Filed: 1969-02-26
Abstract: 1,254,063. Hydroformylation process; cobaltsecondary phosphine - carbon monoxide - complexes. SHELL INTERNATIONAL RESEARCH MAATSCHAPPIJ N.V. 26 Feb., 1969 [28 Feb., 1968], No. 10188/69. Headings C2C and C2P. Aldehydes and/or alcohols are obtained by a hydroformylation process comprising reacting olefines with CO and H 2  in the presence of a novel complex catalyst comprising cobalt, CO and a bicyclic heterocyclic secondary phosphine in which a phosphorus-containing heterocyclic ring with at least five carbon atoms is present. The catalyst is suitably one of the formula [L m Co(CO) n ] x  wherein L is the defined heterocyclic secondary phosphine, m and n are positive integers, m + n is 4, and x is an integer from 1 to 3. The bicyclic secondary phosphines are generically monophosphabicycloalkanes having 8 or 9 ring atoms in which the smallest phosphorus-containing ring contains at least 5 atoms and the phosphorus atom is a member of a bridge linkage and in which the ring carbon atoms are unsubstituted or substituted, e.g. by C 1 -C 4  alkyl groups. The preferred secondary phosphine is monophosphabicyclononane and a particularly preferred catalyst is cobalt-tricarbonyl - 9 - phosphabicyclo 3,3,1 - nonane believed to be dimeric and to have the formula The process may be applied to the hydroformylation of C 2 -C 19  mono-olefines and may be carried out at 28 to 85 atmospheres pressure and at 125‹ to 210‹ C. Examples are given for the hydroformylation of 1-dodecene and propylene, respectively, to form mainly the corresponding primary alcohol in each case. The complexes used as catalyst may be prepared by combining an inorganic or organic cobalt salt with the appropriate phosphine ligand in liquid phase and then heating the solution in an atmosphere of hydrogen and carbon monoxide, the latter step, if desired, being carried out in situ in the hydroformylation process. The catalysts may also be prepared from a carbon monoxide complex of cobalt, e.g. by heating di-cobalt octacarbonyl with a suitable phosphine ligand, e.g. in a hydrocarbon solvent, to replace one or more of the carbon monoxide molecules. The bicyclic heterocyclic secondary phosphines may be obtained by reacting phosphine with an appropriate cyclic hydrocarbon containing two ring non-conjugated and non-homoconjugated double bonds and an example is given for the production of a mixture of 9- phosphabicyclo[4.2.1]nonane and 9-phosphabicyclo[3.3.1]nonane by reacting 1,5-cyclooctadiene with phosphine in deaerated pentane in the presence of azobisisobutyronitrile and in an oxygen-freed pressure vessel. Exposure of the phosphine product to air yields the secondary phosphine oxide and phosphinic acid. Specification 1,109,787 is referred to.
